With oil barges traversing the Hudson River a key issue emerging in the 18th congressional district race, the League of Conversation Voters Action Fund on Friday endorse Democratic Rep. Sean Patrick Maloney’s re-election bid.

“I’m running for re-election to ensure – no matter the zip code – folks in the Hudson Valley have clean drinking water and a safe environment to open a business or raise a family,” said Maloney in a statement.

“I’m proud to have the endorsement of leading environmental groups like the League of Conservation Voters Action Fund because of my extensive record fighting for safe drinking water, leading the effort to clean up pollution in the Hudson River, and preventing environmental catastrophe by making oil train cars safer and keeping oil barges off the Hudson.”

With its endorsement, the group pointed to Maloney’s support for dredging PCB-laden muck from the Hudson River, cleaning up a superfund site in Hopewell Junction and the ongoing efforts surrounding Newburgh’s water contamination.

“Congressman Sean Patrick Maloney has proven himself to be an effective fighter in Congress for the Hudson Valley’s families, economy and environment,” said LCV Action Fund President Gene Karpinski. “He’s seen first-hand the threats climate change poses to communities, knows clean energy solutions will grow the local economy, and has helped to increase the national spotlight around local water contamination issues and protecting the Hudson River.”

Maloney faces Republican Phil Oliva next month. First elected in 2012, Maloney is seeking a third in Congress.
